There are parameter files in known formats for different models, so maybe the required info can be taken directlyor derived from those. > YASim primarily requires only geometry and performance data, > but Andy Ross will need to speak to how well it's math will > scale down. I don't think that the math scaling down is a problem unless fixed-point is being used. If the calcs are in floating point it shouldn't be an issue. My concern was that the fluid dynamics on a small scale wouldn't behave as predicted by simulations designed for larger objects. I'm pretty sure that happens, but I just don't know at what size it becomes an issue. Or maybe I'm just completely off base. Meanwhile, I'll start working on a cable and Linux driver for RC transmitter inputs. -- Grant Edwards [EMAIL PROTECTED] _______________________________________________ Flightgear-users mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-users
